This Elastic Invisible Thread is a very strong superior thread where a single strand can lift an object of over 25 gms. in weight. It comes as a single stripped strand of over 245', dyed black, with no hassles of stripping this from a cluster. Use as much as you wish. You use it to move heavier objects, like silverware or a ball pen, or levitate lighter objects like a cigarette or a tissue rose, an origami bird or a balled up bill. It will stretch to over 5 times its original length. You can also use this to make you own Elastic IT Loops, as per instructions supplied.
